can anyone suggest how to find ISN in encrypted CAS3 + when all keys are lost and the engine driver is EDC16c35?  I've had two such cases and each time someone helped me convert it.  I only know that this ISN is repeatable, e.g. F991ACF991ACF991ACF991ACF991ACF9.  People who  enumerated for me did not need ECU dump.  I don't have Autohex.  I only have Hexprog
